Sigma 85mm F1.4 Art DG HSM
Lens - Sigma Fit:
Sigma 85mm F1.4 Art DG HSM Lens is designed to achieve optical performance
and is ideally suited for creative and artistic applications. This short
telephoto 85mm f/1.4 prime lens is designed for full-frame format Sigma SA-mount
cameras and can also be used with APS-C models where it will provide a 127.5mm
equivalent focal length.

The fast f/1.4 maximum aperture is well-suited for working in low-light
conditions and also provides greater control over the focus position when using
shallow depth of field techniques. A rounded nine-blade diaphragm helps to
produce an attractive out-of-focus quality.

Hyper Sonic Motor (HSM) the lens offers quick and accurate control over the
artistic effects achieved by the lens high quality elements. The lens works
perfectly with auto focus as well as full time manual cameras, without having to
switch camera modes or change settings but just shifting the switch from AF to
MF. The lens Hyper Sonic Motor (HSM) and floating inner focusing system ensures
quick, quiet and precise auto focusing.

This features anti-flare super multi layer coatings reduce lens flare, internal
reflections and light scattering that can occur between the surfaces of its
glass elements. This lens incorporates a brass made bayonet mount which has both
high accuracy and durability.

Two SLD elements, one element with a high rate of anomalous partial dispersion
and a high index of refraction and one aspherical element have been incorporated
within the lens design to correct for chromatic aberrations throughout the
entire focusing range and help to ensure high image sharpness and clarity. It is
suitable to use for sorts, landscapes, portraits, arts, group shots and general
use.

Art DG HSM Lens - Sigma Fit

By taking chromatic aberrations to the absolute
minimum, this lens offers performance that goes beyond, including incredibly
sharp resolution and a beautiful bokeh effect
Image Quality Perfect For Ultra-High-Megapixel Digital Cameras
Incorporates 2 elements made of SLD (Special Low Dispersion Glass) and one
element with a high rate of anomalous partial dispersion and a high index of
refraction
These features help ensure a clear image throughout the plane
The optical system also minimizes sagittal coma flare for outstanding image
quality without streaking - even at wide-open aperture
Elements made of SLD (Special Low Dispersion) glass and an optimized power
distribution help minimize axial chromatic aberration
In the areas in front of and behind the point of focus, the optical system
produces an attractive and natural bokeh effect by producing a smooth gradation
of focus and minimizing streaking
The newly designed Hyper Sonic Motor (HSM) offers 1.3 times the torque of its
predecessor
Even at low speeds, it offers exceptionally stable performance, and the updated
AF algorithm helps ensure nimble autofocus performance
In addition, full-time manual focus override allows the lens to be switched to
manual focus simply by rotating the focus ring—even during continuous AF
The user can quickly find the perfect focus without needing to touch the focus
mode switch
SIGMA USB DOCK makes customization and flexible adjustment possible
